It is estimаted thаt 82% оf cоllege students check their sоciаl media accounts at least once per day. You believe that the proportion could be higher. A random sample of 1012 college students indicates that 83.4% of the sample says that they check their social media accounts at least once per day. Find the 95% confidence interval estimate of the proportion of college students that check their social media accounts at least once per day and explain whether, based on the interval, whether or not the actual percentage being greater than 82% is supported by the interval. We are 95% confident that the true proportion of college students who check their social media account is between [lower] and [upper]. (Round endpoints to three decimal places.) The interval [supports] saying that the actual percentage is greater than 82% because [because].

It has enlisted the vision of statesmen, the genius of inventors, the courage of pioneers, the forcefulness of manufacturers, the initiative of merchants and shipbuilders, and the patient toil of many millions. A whole library could be written on the economic aspects of cotton alone. It could be told in detail, how and why the domination of the field of its manufacture passed from India to Spain, to Holland, and finally to England, which now shares it chiefly with the United States. The interdependence of nations which it has brought about has been the subject of numerous books and articles. Nor is the history of the inventions which have made possible to-day's great production of cotton fabrics less impressive. From the unnamed Hindu genius of pre-Alexandrian days, through Arkwright and Eli Whitney, down to Jacquard and Northrop, the tale of cotton manufacture is a series of romances and tragedies, any one of which would be a story worth telling in detail. Yet, here is a work that is by no means finished. Great inventors who will apply their genius to the improvement of cotton growing and manufacture are still to be born."—From The Fabric of Civilization, 1919 The expansion of cotton farming in the South during the early 1800s was a driving force behind the (5 points)

What report, or what love would be spread about and sown among the natives, touching those Christians, when they left them wounded and desolate?" —From The Letters of Amerigo Vespucci and Other Documents Illustrative of His CareerTranslated by Clements R.
